 Argentina decagun, Clarke, Trans. New Zealand Inst., xi, 1879, 295. 



Height of body oue-eigiitli of its entire le'igtli, with head 4 to 4i in same; eye 3 in head, 

 and less than or e(i[ual to the length of the snout. Ventrals nearly median and under 

 dorsal. Scales min\itely spiuigerous, almost smooth in young. Head sealeless, diaphanous. 



Radial formida: 1). 1(»-12: A. 12; P. 14; Y. 11; L. lat. 52. 



This form is abundant iu shallow water in the Meiliterraneau and Adriatic, where it is 

 often taken by the fisliermen. It is known also ofi Portugal and in the northeastern Atlan- 

 tic from Scotland to 61'= and beyond. In Norwegian waters it occurs in the depths, Oollett 

 having obtained it in 200 lathoms. This distribution is paradoxical, aud is referred to in 

 another place. 



A. sphyrwna spawns in April iu the Mediterranean. 



Giinther considers A. decagon from Hokitika, ISlew Zealand, to be the same form. 

 Giglioli, after studying an extensive series obtained by him at Messina, has decided that 

 A. Uoglossa, C. & V., is al.so identical with A. sphyrana.

Argentina syrtensium, Goode and Bean, Proc. U. S. Nat. Mus., i, 1875, 201. 



Height of body 5.^ in its total length, with head 4 to 4 ^ in same. Eye, 3 in head and 

 longer than snout. Ventrals median, and uuder dorsal. Scales strongly si)inigerous. 



Radial formula: D. 11; A. 14; P. 17; V. 12. Scales, 3J, GO, 4. (A full description with 

 measurements given by Goode and Bean, loc. cit.) 



This form occurs in Norway at depths of 100 fathoms and less. The first taken in North 

 America — the tyi^e of A. si/rtensiam, Goode and Bean (U. S. N. M , No. 21624) — was found 

 in the stomach of a rhycix from Sable Island Bank, in 200 fathoms. In July, ISOl, a 

 specimen 18 inches long (U. S. N. M., No. 4370S) was caught by a boy with a hook and line 

 in the harbor of Belfast, ]Me. Another, No. 37801, 1.5 inches long, was taken at Biddeford 

 Pool, Maine. This distribution is even more pnzzling than that of A. uphyrwnu. 



ARGENTINA STRIATA, Goode and Bean, n. s. (Figure 62.) 



The height of the body is contained 7 times in its total length ; the length of the head 

 3 times in total length. The eye is contained 2J times in the length of the head, and is 

 longer than the conical snout. Ventrals nearly median; their insertion under the penulti- 

 mate dorsal rays. Scales in the lateral line obliquely striate. Tongue with teeth. Origin 

 of the dorsal equidistant between snout and root of caudal. There appears to have been a 

 silvery, longitudinal band nnder the lateral line. 



Radial formula: I). 10; A. 11; P. 17; V. 14. 



The specimens studied were denuded of scales, but the impressions indicate that there 

 were 51 in the lateral line, 4 above and 4 below. The specimens (No. 4.'J858, U. S. N. M.) 

 were obtained by the Albatross from station 2402 in 28^ 36' N. lat., S.j^ 33' 30" W. Ion., at 

 a depth of 111 fathoms. 



Aryentina elonyata, Hutton (Annals and Magazine of Natural History, iii, 1879, 53. — 

 Voy. Challenger, xxii, 218), was obtained at Port Campbell, New Zealand.
